Eliminating the Volume of Spam E-Mails Using a Hashcash-Based Solution.

The article presents information on how to eliminate the volume of spam e-mails using other than traditional methods. Spoofing has been a well known technique, often used by spammers to make them harder to trace. As the spam filters and virus scanners can eliminate only a certain amount of spam, Simple Mail Transfer Protocol (SMTP) allows these e-mail headers to be faked and does not allow for the sender to be authenticated as the real sender of the message. SMTP is the basic mailing protocol used by servers to send e-mail messages to each other, which defines how the conversation should take place and the format of the data that is exchanged during the conversation. Information on an alternative for spamming unwanted mails have also been offered in the article. That alternate method is a Hashcash-based method, in which a textual stamp to the header of an e-mail is added to prove that the sender has expended a certain amount of CPU time calculating the stamp prior to sending the e-mail. Detailed information on the hashcash based spamming solution is offered in the article.
